Clinical Predictive Model of Multidrug Resistance in Neutropenic Cancer Patients with Bloodstream Infection Due to Pseudomonas aeruginosa.

We aimed to assess the rate and predictive factors of bloodstream infection (BSI) due to multidrug-resistant (MDR) Pseudomonas aeruginosa in neutropenic cancer patients. We performed a multicenter, retrospective cohort study including oncohematological neutropenic patients with BSI due to P. aeruginosa conducted across 34 centers in 12 countries from January 2006 to May 2018. A mixed logistic regression model was used to estimate a model to predict the multidrug resistance of the causative pathogens. Of a total of 1,217 episodes of BSI due to P. aeruginosa, 309 episodes (25.4%) were caused by MDR strains. The rate of multidrug resistance increased significantly over the study period (P = 0.033). Predictors of MDR P. aeruginosa BSI were prior therapy with piperacillin-tazobactam (odds ratio [OR], 3.48; 95% confidence interval [CI], 2.29 to 5.30), prior antipseudomonal carbapenem use (OR, 2.53; 95% CI, 1.65 to 3.87), fluoroquinolone prophylaxis (OR, 2.99; 95% CI, 1.92 to 4.64), underlying hematological disease (OR, 2.09; 95% CI, 1.26 to 3.44), and the presence of a urinary catheter (OR, 2.54; 95% CI, 1.65 to 3.91), whereas older age (OR, 0.98; 95% CI, 0.97 to 0.99) was found to be protective. Our prediction model achieves good discrimination and calibration, thereby identifying neutropenic patients at higher risk of BSI due to MDR P. aeruginosa The application of this model using a web-based calculator may be a simple strategy to identify high-risk patients who may benefit from the early administration of broad-spectrum antibiotic coverage against MDR strains according to the local susceptibility patterns, thus avoiding the use of broad-spectrum antibiotics in patients at a low risk of resistance development.

[Management of hyperglycemia in the non-critical hospitalized patients with oral feeding]. / Manejo de la hiperglucemia en el paciente hospitalizado no crítico con alimentación oral.

A 67-year-old woman with a history of hypertension, hyperlipidemia and 6 years of evolution of type 2 diabetes mellitus presented with fever, purulent sputum and right chest pain. She was on treatment with metformin 850 mg/bid, glimepiride 4 mg/day, candesartan 16 mg/day, atorvastatin 10mg/day and acetylsalicylic acid 100mg/day. Standing out in the physical examination was blood pressure 90/50 mmHg, temperature 38.6 °C, pulse 112/min, respirations 24/min, weight 8 5 kg, height 1.68 m. She had crackling rales in the right lung-base and edema in lower limbs. The blood analysis showed leukocytosis, glucose 348 mg/dl, urea 70 mg/dl, creatinine 1.5mg/dl and HbA1c 8.4%. A chest x-ray revealed condensation in the lower lobe of the right lung. Antibiotic treatment was begun, maintaining an oral diet from admission. What is the best strategy regarding the treatment of this patient's hyperglycemia, its management and what evidence is there on this subject?

Co-infections and superinfections complicating COVID-19 in cancer patients: A multicentre, international study.

BACKGROUND: We aimed to describe the epidemiology, risk factors, and clinical outcomes of co-infections and superinfections in onco-hematological patients with COVID-19. METHODS: International, multicentre cohort study of cancer patients with COVID-19. All patients were included in the analysis of co-infections at diagnosis, while only patients admitted at least 48 h were included in the analysis of superinfections. RESULTS: 684 patients were included (384 with solid tumors and 300 with hematological malignancies). Co-infections and superinfections were documented in 7.8% (54/684) and 19.1% (113/590) of patients, respectively. Lower respiratory tract infections were the most frequent infectious complications, most often caused by Streptococcus pneumoniae and Pseudomonas aeruginosa. Only seven patients developed opportunistic infections. Compared to patients without infectious complications, those with infections had worse outcomes, with high rates of acute respiratory distress syndrome, intensive care unit (ICU) admission, and case-fatality rates. Neutropenia, ICU admission and high levels of C-reactive protein (CRP) were independent risk factors for infections. CONCLUSIONS: Infectious complications in cancer patients with COVID-19 were lower than expected, affecting mainly neutropenic patients with high levels of CRP and/or ICU admission. The rate of opportunistic infections was unexpectedly low. The use of empiric antimicrobials in cancer patients with COVID-19 needs to be optimized.

[Appropriateness of antimicrobial prescriptions in the emergency department of a tertiary hospital]. / Adecuación de las prescripciones antimicrobianas realizadas en el área de urgencias de un hospital de tercer nivel.

OBJECTIVE: Antibiotics are widely prescribed in the Emergency Department (ED), representing 26-62% of outpatient antibiotic prescriptions. Around 40% of antibiotic prescriptions in hospitalized patients are inappropriate or unnecessary. The aim of the study was to assess the appropriateness of antibiotic prescriptions according to local empirical antibiotic treatment guidelines, in the ED of a tertiary hospital. METHODS: Observational, retrospective study including patients attending the ED in November 2016, with an antibiotic prescription, excluding those from residents. RESULTS: A total of 676 patients were included, 57.1% women, mean age 47.4 ± 21.2 years. Patient's diagnoses were 27.2% urinary tract infections (UTI), 24.1% lower respiratory tract infections, 15.4% skin and soft tissue infections (SSTI), 13.8% upper respiratory tract infections, 11.8% oral infections, 2.7% genital/sexually transmitted infections, 1.6% gastrointestinal infections, 0.3% ocular infections and 3.1% other. The most prescribed antibiotic families were: 44.1% penicillins, 21.3% fluoroquinolones. The most prescribed antibiotics were: fosfomycin trometamol in UTI (32.1%), levofloxacin in lower respiratory tract (46.2%) and amoxicillin/clavulanate in oral infections (71.6%), SSTI (62.5%) and upper respiratory tract (46.6%). In 56.8% (384) of the prescriptions antibiotics were indicated. An appropriated antibiotic was selected in 62% (238) of the prescriptions. Appropriated dosage and duration were selected in 82.8% (197) and 45.4% (108) of the prescriptions, respectively. CONCLUSIONS: Appropriateness of antibiotic prescriptions was low, mainly due to an overuse of antibiotics when not indicated, broad spectrum and incorrect treatment duration. These data reinforce the need to enhance adherence to local empirical antibiotic treatment guidelines by developing an antimicrobial stewardship program in the ED.
